Unilever dropped the lawsuit Thursday. The company didn't give a reason why.

The lawsuit claimed that Just Mayo does not meet the legal definition of mayonnaise since it isn't made with eggs. Unilever also took issue with the Just Mayo label, which contains an image of an egg, and said the vegan sandwich spread was inferior in taste and "performance" to Best Foods and Hellman's mayo.

Critics started a petition on Change.org calling on Unilever to "stop bullying sustainable food companies." The petition received more than 112,000 signatures.

Unilever said in a statement that it withdrew the suit so that Hampton Creek "can address its label directly with industry groups and appropriate regulatory authorities."

Hampton Creek, which also makes egg-free cookie dough, is on a mission to develop plant-based alternatives to products made with eggs. The company argues that current egg production is unsustainable because it requires farms to produce vast amounts of chicken feed, using up valuable resources such as water and land.

The company recently raised $90 million in funding from private investors, including Marc Benioff, founder and CEO of Salesforce, and Eduardo Saverin, co-founder of Facebook(FB).
